Abstract
The printer records images in the form of dots on electrical discharge-sensitive paper. A plurality of styli are mounted on a rotor. The paper is in strip form and is fed continuously through a curved guide in a direction perpendicular to the plane of rotation of the rotor. Each stylus is energized by a voltage sufficient to create an electrical discharge between the paper and the stylus, in accordance with a code supplied from an electrical memory in which the codes for the character images are stored. This divisional patent is directed to the feature whereby words and sentences are formed longitudinally on the strip. Several lines of text can be formed on the strip, and a whole page of text can be printed relatively quietly and at a relatively high speed and low cost. Characters forming one message are stored in memory. Then they are read out in the sequence in which characters from different lines are to appear in transverse columns. The length of the lines can vary over a wide range.
